TIL I was setting my water heater wrong for years

I always kept my water heater at 140 degrees thinking it was better. My gas bill was high and my pipes were getting noisy. A plumber from Rio Rancho came out for a different fix and asked why it was set so hot. He told me 120 degrees is plenty and safer, especially with kids. He said at 140, I was wasting about $60 a year just on standby heat loss. I turned it down last week and the hot water is still fine. What's the right temp you all use to save money but still get a good shower?

Actually, 140 is needed for some dishwashers without a booster heater.

140 seems crazy hot" is what gets me, like that can't be safe for the pipes.

Absolutely right, we had that exact problem in our old place. The dishwasher just wouldn't get things truly clean and left a weird film. A plumber finally asked about our water heater temp and that was the whole fix. Cranking it up made a huge difference. It's one of those things you don't know until you run into it.
